Description

本発明は、車両用ドア開閉装置に関するものである。   The present invention relates to a vehicle door opening and closing device.

従来、伸縮可能な軸形状を有して車両のボディとドアとの間に介在されることによりドアの開位置を保持可能な支持部材を備えた車両用ドア開閉装置がある。通常、このような車両用ドア開閉装置において、支持部材は、ドア及びボディに対して、その軸方向両端が回動自在に連結される。そして、その回動連結点を中心に相対回動しつつ伸縮することによって、車両のドアを開閉動作させることが可能となっている。   2. Description of the Related Art Conventionally, there is a vehicle door opening and closing device that includes a support member that has a shaft shape that can be expanded and contracted and can be held between a vehicle body and a door so as to hold an open position of the door. Usually, in such a vehicle door opening and closing device, both ends in the axial direction of the support member are rotatably connected to the door and the body. And it is possible to open and close the door of the vehicle by expanding and contracting while relatively rotating around the rotation connecting point.

例えば、特許文献1には、その支持部材内に当該支持部材を伸縮させる駆動装置が内蔵された構成が開示されている。そして、その支持部材の軸端部には、ドア側及びボディ側の各連結部位に設けられる球状嵌合部に嵌合することにより上記回動連結点を形成するソケットが設けられている。   For example, Patent Document 1 discloses a configuration in which a driving device for expanding and contracting the support member is incorporated in the support member. And the socket which forms the said rotation connection point is provided in the axial end part of the supporting member by fitting in the spherical fitting part provided in each connection part of a door side and a body side.

即ち、このように球状嵌合部にソケットを嵌合してなるボールジョイントにより回動連結点を形成することによって、簡素な構成にて、円滑に支持部材を回動させることができる。そして、その高い組付け性を活かして、車両に対する取り付け作業の効率化を図ることができる。   In other words, the support member can be smoothly rotated with a simple configuration by forming the rotation connection point by the ball joint formed by fitting the socket to the spherical fitting portion. And the efficiency of the attachment operation | work with respect to a vehicle can be achieved using the high assembly | attachment property.

Make it work. Further, the back door 3 is closed by reducing the axial length of each support member 10. Then, based on the elastic force of the compression coil spring 30 accommodated in the cylinder, the open position of the back door 3 can be maintained by maintaining the axial length (extension / contraction length) of each support member 10. It has become.

(支持部材の連結構造)
次に、上記のように構成された各支持部材10の連結構造について説明する。
図4に示すように、バックドア3及びボディ4のパネル表面Sには、それぞれ、上記各支持部材10との連結部位αを構成する連結ブラケット32が設けられている。具体的には、これらの連結ブラケット32には、パネル表面Sに対して略直交する方向に突出する軸部33と当該軸部33の先端に設けられた球頭部34とを備えてなるボールスタッド35が設けられている。そして、各支持部材10の軸端部31(31a,31b)には、それぞれ、その球状嵌合部としての球頭部34に嵌合することにより各支持部材10の回動連結点P(P1,P2)を形成するソケット40(40a,40b)が設けられている。
(Connecting structure of support members)
Next, the connection structure of the support members 10 configured as described above will be described.
As shown in FIG. 4, on the panel surface S of the back door 3 and the body 4, connection brackets 32 constituting connection portions α with the respective support members 10 are provided. Specifically, these connecting brackets 32 are balls each including a shaft portion 33 projecting in a direction substantially orthogonal to the panel surface S and a ball head 34 provided at the tip of the shaft portion 33. A stud 35 is provided. The shaft end portion 31 (31a, 31b) of each support member 10 is fitted to a spherical head 34 serving as a spherical fitting portion, thereby turning the connection point P (P1) of each support member 10. , P2), sockets 40 (40a, 40b) are provided.

詳述すると、図4〜図7に示すように、第1ハウジング21側及び第2ハウジング22側の各ソケット40(40a,40b)は、それぞれ、軸端部31(31a,31b)に取着される略円柱状の軸部41と、上記ボールスタッド35の球頭部34に嵌合する嵌合凹部42を有して軸部41の先端に設けられたソケット部43とを備えている。   Specifically, as shown in FIGS. 4 to 7, the sockets 40 (40a, 40b) on the first housing 21 side and the second housing 22 side are respectively attached to the shaft end portions 31 (31a, 31b). A substantially cylindrical shaft portion 41 and a socket portion 43 provided at the tip of the shaft portion 41 with a fitting recess 42 that fits into the ball head 34 of the ball stud 35.

本実施形態のソケット部43は、軸部41の軸線に対して略平行する平坦面43aを有した略半球状の外形を有しており、嵌合凹部42は、そのソケット部43の平坦面43aに凹設されている。また、略円形状をなす嵌合凹部42の開口部42aには、その内周に円環状の嵌合溝44が凹設されるとともに、この嵌合溝44内には、その円環形状の一部に破断部分を有するCリング45が嵌着されている。そして、本実施形態では、その弾性変形により拡縮可能なCリング45によって、嵌合凹部42の開口部42aを小径化することにより、その嵌合凹部42内にボールスタッド35の球頭部34を保持する構成となっている。   The socket portion 43 of the present embodiment has a substantially hemispherical shape having a flat surface 43 a substantially parallel to the axis of the shaft portion 41, and the fitting recess 42 is a flat surface of the socket portion 43. It is recessed in 43a. In addition, an annular fitting groove 44 is recessed in the inner periphery of the opening 42a of the fitting recess 42 having a substantially circular shape, and the fitting groove 44 has an annular shape. A C-ring 45 having a broken part is fitted. In this embodiment, the diameter of the opening 42a of the fitting recess 42 is reduced by the C ring 45 that can be expanded and contracted by the elastic deformation, so that the ball head 34 of the ball stud 35 is placed in the fitting recess 42. It is the structure to hold.

図8に示すように、本実施形態の嵌合溝44は、当該嵌合溝44内に配置された保持リングとしてのCリング45が軸方向移動可能な溝幅(図8中、上下方向の長さ)を有している。また、嵌合溝44は、その嵌合凹部42の開口部42a側から底部42b側に向かって拡径するテーパ面44sを有している。そして、Cリング45は、嵌合溝44における開口部42a側の側壁44aに当接することにより、その開口部42a側への軸方向移動、つまり嵌合溝44から脱離する方向の軸方向移動が規制されるようになっている。   As shown in FIG. 8, the fitting groove 44 of the present embodiment has a groove width (in FIG. 8, the vertical direction in FIG. 8) in which the C ring 45 as a holding ring arranged in the fitting groove 44 can move in the axial direction. Length). Further, the fitting groove 44 has a tapered surface 44 s whose diameter increases from the opening 42 a side to the bottom portion 42 b side of the fitting recess 42. Then, the C ring 45 abuts on the side wall 44a on the opening 42a side in the fitting groove 44, thereby moving in the axial direction toward the opening 42a, that is, moving in the direction away from the fitting groove 44. Are now regulated.

ここで、本実施形態では、開口部42a側の側壁44a近傍における嵌合溝44の内径r1は、その嵌合凹部42に嵌合する球頭部34の直径r0(図4参照)を超えてCリング45の内径r3が拡径できない値に設定されている。そして、底部42b側の側壁44b近傍における嵌合溝44の内径r2は、そのCリング45の内径r3が球頭部34の直径r0以上に拡径することが可能な値に設定されている。   Here, in the present embodiment, the inner diameter r1 of the fitting groove 44 in the vicinity of the side wall 44a on the opening 42a side exceeds the diameter r0 (see FIG. 4) of the spherical head 34 fitted in the fitting recess 42. The inner diameter r3 of the C ring 45 is set to a value that cannot be expanded. The inner diameter r2 of the fitting groove 44 in the vicinity of the side wall 44b on the bottom 42b side is set to a value that allows the inner diameter r3 of the C ring 45 to be larger than the diameter r0 of the spherical head 34.

即ち、バックドア3及びボディ4に対する各支持部材10の取り付け時、嵌合溝44内に配置されたCリング45は、その開口部42aから嵌合凹部42内に挿入される球頭部34に押圧されることによって、押し広げられるように拡径しつつ、嵌合溝44内を開口部42a側から底部42b側に向かって移動する(図8中、下側から上側に移動)。そして、球頭部34は、このCリング45の拡径によって、その最大径部分(図1参照、直径r0を示した部分)がCリング45を越えて嵌合凹部42の底部42b側に移動することが可能となっている。   That is, when each support member 10 is attached to the back door 3 and the body 4, the C-ring 45 disposed in the fitting groove 44 is moved from the opening 42 a to the spherical head 34 inserted into the fitting recess 42. By being pressed, the inside of the fitting groove 44 is moved from the opening 42a side toward the bottom 42b side while expanding the diameter so as to be expanded (moved from the lower side to the upper side in FIG. 8). Then, due to the diameter expansion of the C-ring 45, the maximum diameter portion (see FIG. 1, the portion indicated by the diameter r 0) of the spherical head 34 moves beyond the C-ring 45 and moves to the bottom 42 b side of the fitting recess 42. It is possible to do.

また、Cリング45は、球頭部34の最大径部分よりも嵌合凹部42の開口部42a側に配置されることによって、その球頭部34の球面に沿うように縮径しつつ、嵌合溝44内を底部42b側から開口部42a側に向かって移動する(図8中、上側から下側に移動)。そして、その側壁44aに当接して開口部42a側への軸方向移動が規制されることにより、当該開口部42a側に向かう球頭部34の移動を規制する。即ち、当該球頭部34の抜脱を規制して、その嵌合凹部42内に球頭部34を保持することが可能となっている。   In addition, the C-ring 45 is disposed closer to the opening 42 a of the fitting recess 42 than the maximum diameter portion of the ball head 34, thereby reducing the diameter along the spherical surface of the ball head 34 and fitting. It moves in the joint groove 44 from the bottom 42b side to the opening 42a side (moves from the upper side to the lower side in FIG. 8). Then, the movement of the spherical head 34 toward the opening 42a is restricted by abutting the side wall 44a and restricting the axial movement toward the opening 42a. That is, it is possible to hold the ball head 34 in the fitting recess 42 by regulating the removal of the ball head 34.

さらに詳述すると、図6に示すように、各支持部材10における第1ハウジング21側の軸端部31aには、当該第1ハウジング21の底部21bから軸方向に突出する略円柱状の凸状嵌合部51が形成されている。そして、この軸端部31aに取着されるソケット40aには、その凸状嵌合部51が挿入される嵌合穴52が形成されている。   More specifically, as shown in FIG. 6, the shaft end portion 31 a on the first housing 21 side of each support member 10 has a substantially cylindrical convex shape that protrudes in the axial direction from the bottom portion 21 b of the first housing 21. A fitting portion 51 is formed. A fitting hole 52 into which the convex fitting part 51 is inserted is formed in the socket 40a attached to the shaft end part 31a.

具体的には、ソケット40a側の嵌合穴52は、その軸部41aの軸端面41sから当該軸部41aの軸線に沿うように(図6中、右側に向かう方向)に穿設されている。また、この嵌合穴52が形成されたソケット40aの軸部41aには、その軸線に交差する方向(図6中、上下方向)において当該軸部41aを貫通、詳しくは嵌合穴52の壁部53を貫通する貫通孔54が形成されている。更に、この嵌合穴52内に挿入される軸端部31a側の凸状嵌合部51にも、その軸部41aに形成された貫通孔54に対応する位置に、その軸線に交差する方向(図6中、上下方向)において当該凸状嵌合部51を貫通する貫通孔55が形成されている。そして、これらの貫通孔54,55内には、その嵌合穴52の壁部と凸状嵌合部51との間に跨って配置されることにより嵌合穴52内に凸状嵌合部51を固定する固定部材としての固定ピン56が挿入されている。   Specifically, the fitting hole 52 on the socket 40a side is drilled from the shaft end surface 41s of the shaft portion 41a along the axis of the shaft portion 41a (in the direction toward the right side in FIG. 6). . Further, the shaft portion 41a of the socket 40a in which the fitting hole 52 is formed penetrates the shaft portion 41a in the direction intersecting the axis (vertical direction in FIG. 6), and more specifically, the wall of the fitting hole 52 A through hole 54 penetrating the portion 53 is formed. Furthermore, the convex fitting part 51 on the side of the shaft end part 31a inserted into the fitting hole 52 also has a direction crossing the axis line at a position corresponding to the through hole 54 formed in the shaft part 41a. A through hole 55 penetrating the convex fitting portion 51 is formed in the vertical direction in FIG. And in these through-holes 54 and 55, a convex fitting part is inserted in the fitting hole 52 by arrange | positioning between the wall part of the fitting hole 52, and the convex fitting part 51. A fixing pin 56 as a fixing member for fixing 51 is inserted.

尚、本実施形態では、嵌合穴52の内径は、凸状嵌合部51の直径と略等しく設定されている。また、固定ピン56の軸長は、軸部41aの直径と略等しく設定されている。そして、ソケット40aには、その軸部41aの外周を包囲することにより各貫通孔54,55内に固定ピン56を保持するカバー57が取着されている。   In the present embodiment, the inner diameter of the fitting hole 52 is set substantially equal to the diameter of the convex fitting portion 51. The axial length of the fixed pin 56 is set to be approximately equal to the diameter of the shaft portion 41a. The socket 40a is attached with a cover 57 that holds the fixing pin 56 in each of the through holes 54 and 55 by surrounding the outer periphery of the shaft portion 41a.

一方、図7に示すように、各支持部材10における第2ハウジング22側の軸端部31bには、当該第2ハウジング22の底部22bから軸方向に突出する螺子軸61が設けられている。そして、この軸端部31bに取着されるソケット40bには、その螺子軸61が螺合される螺子穴62が形成されている。   On the other hand, as shown in FIG. 7, a screw shaft 61 protruding in the axial direction from the bottom portion 22 b of the second housing 22 is provided at the shaft end portion 31 b on the second housing 22 side in each support member 10. A screw hole 62 into which the screw shaft 61 is screwed is formed in the socket 40b attached to the shaft end portion 31b.

具体的には、ソケット40b側の螺子穴62は、その軸部41bの軸端面41sから当該軸部41bの軸線に沿うように(図7中、左側に向かう方向)に螺設されている。また、軸端部31b側の螺子軸61は、第2ハウジング22の底部22bに形成された螺子孔63に対し、その底部22bを貫通するように筒内側(同7中、右側)からボルト64を螺着することにより形成される。即ち、この螺子軸61を構成するボルト64は、螺子孔63を介してソケット40bの螺子穴62に螺入される。そして、これにより、ソケット40bは、その軸部41bが第2ハウジング22の底部22bから突出する態様で、各支持部材10の軸端部31bに締結されている。   Specifically, the screw hole 62 on the socket 40b side is screwed from the shaft end surface 41s of the shaft portion 41b along the axis of the shaft portion 41b (in the direction toward the left side in FIG. 7). Further, the screw shaft 61 on the shaft end portion 31b side is connected to the screw hole 63 formed in the bottom portion 22b of the second housing 22 with a bolt 64 from the inside of the cylinder (right side in FIG. 7) so as to penetrate the bottom portion 22b. It is formed by screwing. That is, the bolt 64 constituting the screw shaft 61 is screwed into the screw hole 62 of the socket 40b through the screw hole 63. As a result, the socket 40b is fastened to the shaft end portion 31b of each support member 10 in such a manner that the shaft portion 41b protrudes from the bottom portion 22b of the second housing 22.

尚、本実施形態では、第2ハウジング22の底部22bには、ソケット40b側の軸部41bにおける軸端面41s近傍が挿入される凹部66が形成されている。そして、この凹部66内には、当該凹部66内に挿入された軸部41bの回転を規制する回り止め構造(所謂二面幅嵌合構造)が形成されている。   In the present embodiment, the bottom portion 22b of the second housing 22 is formed with a recess 66 into which the vicinity of the shaft end surface 41s of the shaft portion 41b on the socket 40b side is inserted. And in this recessed part 66, the rotation prevention structure (what is called a two-surface width fitting structure) which controls rotation of the axial part 41b inserted in the said recessed part 66 is formed.

次に、上記各支持部材10の連結構造の作用について説明する。
即ち、ソケット40(40a,40b)の嵌合凹部42に嵌着されたCリング45は、その開口部42aを小径化して当該嵌合凹部42内に挿入された球頭部34の抜脱を規制することにより、当該球頭部34を嵌合凹部42内に保持する。
Next, the effect | action of the connection structure of each said supporting member 10 is demonstrated.
In other words, the C-ring 45 fitted in the fitting recess 42 of the socket 40 (40a, 40b) reduces the diameter of the opening 42a and removes the ball head 34 inserted into the fitting recess 42. By restricting, the ball head 34 is held in the fitting recess 42.

また、ソケット40aは、その軸部41aに形成された嵌合穴52内に、第1ハウジング21側の軸端部31aに形成された凸状嵌合部51を挿入する態様で、その軸端部31aに取着される。そして、ソケット40aは、その嵌合穴52内に挿入された凸状嵌合部51が、当該凸状嵌合部51及びソケット40aの軸部41a(嵌合穴52の壁部53)を貫通する固定ピン56によって嵌合穴52に固定されることにより、第1ハウジング21の軸端部31aに固定される。   Further, the socket 40a has a mode in which the convex fitting portion 51 formed on the shaft end portion 31a on the first housing 21 side is inserted into the fitting hole 52 formed in the shaft portion 41a. It is attached to the part 31a. In the socket 40a, the convex fitting portion 51 inserted into the fitting hole 52 penetrates the convex fitting portion 51 and the shaft portion 41a of the socket 40a (the wall portion 53 of the fitting hole 52). By being fixed to the fitting hole 52 by the fixing pin 56, the shaft end 31a of the first housing 21 is fixed.

そして、その軸部41a(の貫通孔54)及び軸端部31a側の凸状嵌合部51(の貫通孔55)間に介在された固定ピン56を抜脱することによって、球頭部34に嵌合した状態のソケット40を軸端部31aから取り外すことが可能になる。   Then, by removing the fixing pin 56 interposed between the shaft portion 41a (the through hole 54) and the convex fitting portion 51 (the through hole 55) on the shaft end portion 31a side, the ball head 34 is removed. It becomes possible to remove the socket 40 in a state of being fitted to the shaft end portion 31a.

以上、本実施形態によれば、以下のような効果を得ることができる。
(1)各支持部材10の軸端部31には、それぞれ、当該各支持部材10との連結部位αに設けられたボールスタッド35の球頭部34に嵌合することにより各支持部材10の回動連結点P(P1,P2)を形成するソケット40(40a,40b)が設けられる。また、ソケット40の嵌合凹部42には、その開口部42aを小径化して当該嵌合凹部42内に球状嵌合部としての球頭部34を保持可能な保持リングとしてのCリング45が設けられる。そして、ソケット40(40a)は、その球頭部34が嵌合した状態で、支持部材10の軸端部31から取り外し可能に形成される。

Further, the fitting recess 42 of the socket 40 is provided with a C ring 45 as a holding ring capable of holding the spherical head 34 as a spherical fitting portion in the fitting recess 42 by reducing the diameter of the opening 42a. It is done. The socket 40 (40a) is detachable from the shaft end portion 31 of the support member 10 in a state in which the ball head 34 is fitted.

上記構成によれば、ソケット40の嵌合凹部42に設けられたCリング45によって、その嵌合凹部42内に配置された球頭部34の抜脱が規制される。これにより、嵌合凹部42内に球頭部34が保持されることで、その各支持部材10の連結状態を維持することができる。そして、その球頭部34に嵌合した状態のソケット40aを支持部材10の軸端部31aから取り外すことが可能になることで、良好な整備性を確保することができる。   According to the above configuration, the C-ring 45 provided in the fitting recess 42 of the socket 40 restricts the withdrawal of the ball head 34 disposed in the fitting recess 42. Thereby, the connection state of each supporting member 10 can be maintained by holding the ball head 34 in the fitting recess 42. And since it becomes possible to remove the socket 40a of the state fitted to the ball | bowl head 34 from the axial end part 31a of the supporting member 10, favorable maintainability can be ensured.

And the fixing pin 56 which penetrates the wall part 53 and the convex fitting part 51 of the fitting hole 52 is inserted in these through holes 54 and 55.

上記構成によれば、その嵌合穴52の壁部53と凸状嵌合部51との間に跨って配置される固定ピン56によって、嵌合穴52内に凸状嵌合部51が固定される。これにより、各支持部材10の軸端部31aに対するソケット40aの軸方向移動、及びその軸線回りの回動が規制される。即ち、この固定ピン56は、抜け止め部材及び回り止め部材として機能する。そして、その貫通孔54,55から固定ピン56を抜脱することによって、ソケット40aが球頭部34に嵌合した状態においても、容易且つ速やかに、その軸端部31aからソケット40aを取り外すことができる。   According to the above configuration, the convex fitting portion 51 is fixed in the fitting hole 52 by the fixing pin 56 disposed between the wall portion 53 of the fitting hole 52 and the convex fitting portion 51. Is done. Thereby, the axial movement of the socket 40a with respect to the shaft end portion 31a of each support member 10 and the rotation around the axis are restricted. That is, the fixing pin 56 functions as a retaining member and a detent member. Then, by removing the fixing pin 56 from the through holes 54 and 55, the socket 40a can be easily and quickly removed from the shaft end portion 31a even when the socket 40a is fitted to the ball head 34. Can do.
